Hi Ankit Bhai I love your work and I have learnt lot from ur videos as from non IT background I have learnt lot from ur end and started giving interviews for IT sector
Today I had interview and they had asked one question on sql
Like we have a table with row as string
Table1
A
B
C now they need output as
Abc
Bac
Cab
Bac like wise plse help me making this video it will great help to me and other like me
What's the logic here .?
Even I'm clue less they ask me to get column as crossponding each letter
at around 16:50 time of the video, NULL has been replaced by sales. So, we have got the same value in row1 for both sales and previuos_year_sales columns. But, logically speaking there’s no year previous to 2018, so the previous_year_sales should have been 0, isn’t it. Please clarify. Thanks.
If we consider it has 0 then growth will be very high. The same means no growth as the company just started .
@@ankitbansal6 Appreciate the quick response.
sir dataset plz
Hello Ankit, which screen recording application do you use? And if I am on a call with some, will the recording take their sound as well. Thanks

2-2021 | Null | Null
3-2021 | A1 | 210
3-2021 | B1 | 230
4-2021 | Null | Null
output:
Year | Vendor | Amt
1-2021 | A | 100
1-2021 | B | 200
1-2021 | C | 300
2-2021 | A | 100

3-2021 | B1 | 230
4-2021 | A1 | 210
4-2021 | B1 | 230
How to solve this question Ankit Sir
with cte as (
select * , lag(grp) over (order by date) as prev_grp from (select date, group_concat(vendor) as grp from sales
group by date) as x
)
, cte2 as
(select date, grp from cte
union all
select date, prev_grp as grp from cte
)
,cte3 as (
select * from cte2
where grp is not null
)
SELECT
date,
SUBSTRING_INDEX(SUBSTRING_INDEX(grp, ',', n), ',', -1) AS grp
FROM cte3
CROSS JOIN
(SELECT 1 AS n UNION ALL SELECT 2 UNION ALL SELECT 3 UNION ALL SELECT 4) AS numbers
WHERE
n
